- In the process of reflow oven, the components are not directly impregnated in the molten solder, so the thermal shock to the components is small (due to the different heating methods, the thermal stress to the components will be relatively large in some cases).
- Can control the amount of solder applied in the leading process, reduce welding defects such as virtual welding, bridge, so the welding quality is good, the consistency of solder joint is good, high reliability.
- If accurate location of the leading process on the PCB solder casting and put the position of the components have a certain deviation, in the process of reflow soldering machine, when all components of the welding end, pin and the corresponding solder wetting at the same time, due to the effect of the surface tension of the molten solder, produce the orientation effect, automatically correcting deviation, the components back to approximate the exact location.
- SMT Reflow oven is a commercial solder paste that ensures the correct composition and generally does not mix with impurities.
- Local heating source can be used, so different welding methods can be used for welding on the same substrate.
- The process is simple and the workload of repair is very little.
